🍀 Dernord Sanitary Female Clover Clamp Review

I bought two 1 1/2" TC X FNPT fittings. They are useless. The threads are not threaded properly. Only three threads are allowed on the male fitting, regardless of the amount of tape, grease or Threaded the sealant I use Disappointed as the other Dernod fittings were fine.

Dernord 1.5" Triple Clover to 1/2 FNPT Adapter. Non-NPT Threads: Same pitch but not tapered .every male NPT fitting I fatigued would rattle when connected until the unthreaded sections were compressed.That's not how the NVV is supposed to work.I'm guessing they think the US folks put it with a dozen layers of PTFE -Wrap tape until airtight for low/no pressure applications and they don't care if it's sanitary or not.

While Dernord's prices are good and the quality is acceptable, I just can't get over their failure to get it right to fulfill order. Two orders recently with incorrect parts. I returned them and requested the correct parts, in this case TC for female NPT 1/4" fittings. What did I get? A correct part along with a male 1/2" NPT TC fitting. This was one of the fittings I returned! I give up. I'm happy to pay a little more to get the right part the first time. I'm done.
